HP Pavillion Laptop — Extended Warranty of laptop

I want to make a complain regarding the negligence of HP service centre in Chennai-RT Outsourcing Service Ltd., Peters Road Service Centre.
I went to this service centre to avail my extended waranty service which is going to exipre in near future(expiry date May 2nd 2009). But the service centre people told that there is no service extension done from your side and the waranty expired in year 2007. I showed them all the details but they were not ready to accept. They behavior was ill-mannered.

I also told them that I have already availed the service of extended warany from this centre in recent past. But they were not ready to accept this.

The worst part was the top engineer behaved in a very ill mannered way.

This is the last product that I have bought from HP, in near future never I will suggest anyone to buy HP products. As everyone know, word of mouth is also a way to promote a products of vendor and it can also works in reverse manner.
